MULTI-STAGE CHARGE RE-USE ANALOG CIRCUITS

摘要

A linear transform can be performed using a passive analog multi-stage charge re-use linear transform circuit. The passive analog multi-stage charge re-use linear transform circuit transforms an input analog circuit to generate a transformed analog output signal. The passive analog multi-stage charge re-use linear transform circuit may be included in a software defined radio (SDR), where the transformed analog output signal may be output to an analog-to-digital converter (ADC) of the SDR device so as to enable the ADC to perform wideband spectrum sensing. The passive analog multi-stage charge re-use linear transform circuit may also be included in a beamforming device so as to enable the device to perform spectral shifting and spatial shifting of signals. This passive analog multi-stage charge re-use linear transform circuit may promote reduced power consumption in comparison to other circuits while also supporting wideband applications at high sampling rates.
